Extract from Wikipedia article: Ischnoderma resinosum is a species of fungus in the family Fomitopsidaceae. Commonly known as the late fall polypore, resinous polypore, or benzoin bracket, this shelf mushroom is 7–25 cm (3–10 in) across, velvety, dark red/brown, aging black. Its spongy but tough, sweet smelling flesh exudes a red liquid when young. This fungus fruits on hardwood logs and stumps in late autumn. A widely distributed species, it has been recorded from Africa, Asia, Europe, and North America.

Ischnoderma resinosum is a perennial, bracket-like fungus that grows on deciduous trees, particularly oak and elm. In East and Central Texas, it typically fruits in late summer to early fall, producing brown to grayish-brown caps with a resinous, sticky upper surface and a white to cream-colored pore surface underneath. The fungus can be found on stumps, logs, and living trees, often in shaded, moist areas near streams or rivers. Its range in the region includes the eastern deciduous forests and woodland edges of East Texas, as well as the riparian corridors and urban woodlands of Central Texas.
